Copypasta description from DA:

Hey everyone! Long time no post! XD

Here we have an alternate form for Kat! Introducing Katsuki the Foxtaur! X3 I'm now a big fat centaurian fox, weighing in at around 1,200 pounds!

Again, this will be an alternate form for me, may sometimes appear as this in RPs or drawings. I've toyed with the idea for a couple years, actually. Finally decided to draw it again X3 But remember, I'll normally be in standard fox form. This is just a fun thing~
